PNEUMATIC TIRE.

Specication of Letters Patent.

Patented Dec. 1?, i918.

' Application filed J une 23, 1915. Serial No.v 35,887.

` To all 'whom it may concern:

clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which j it appertains to make and use the same.

AThis invention relates to pneumatic tires, and more particularly to anfinternal armor especially designed for .use in connection with pneumatic tires for protecting the inner tube and preventing rim cutting of the eas? 'ing due' to striking or running over sharp objects upon the road.

yThe invention has for its primary object to provide an improved armor for pneumatictires including essentially a band constructed of spring sheet metal having the V free ends detachably connected, and' means- -for protecting the inner tube of the tire against injury thereto by the connecting or fastening means for the' ends of thearmor.-

band.

Another object is the provision of a fab- 'ric liner adapted 'to be arranged in the tire and against the annular armor element to insure against Contact of the inner tube W'ith the metallic surface of the armor band.

With these and other objects, in view, the

Ainvent-ion consists in the novel construction',

arrangement and formation of parts as will be hereinafter Specifically described,claimefl and illustrated in the accompanying drawing, in which: I

Figure 1 represents-a perspective view of the improved tire armor removed.

. ,Fig'Q represents a transverse sectional View through a pneumatic tire casing illns' trating the improved tire a'rmor applied -to use and, U

Fig. 3 represents a fragmental interior pan view of the adjacent overlapped ends of the band constituting the tire armor.

Referringto the drawing in detail, where.

in similar reference numerals designate corresponding' parts throughout the several views, the numeral 5 indicates a strip of lsheetl steel or similar resilient metal, which is curved transversely to conform with the inner surface of the-tread portion ot' a tire casing, as clearly illustrated in Fig. 2. A pair 'ofrivets 6 are secured to one end 7 of the strip 5 and are formed at their inner extremities. with heads 8 spaced avdistanceA from the end 7 approximately equa-l to the vthickness of the 4other end 9 of the strip.

The end is formed with a p'air of' spaced elongated slots or openings 1.0 having Aone end enlarged,- as indicated at 11, to receive the heads f8 of the rivets, the relatively narrow'portions of the openings 10 being of approximately the saine width as the diameters of the shanks 6.

Guard plates 12 of elongated concave conveX formation are .provided with lateral flanges 13 secured toY the end 9 of the strip or band 5j by rivets 14 or equivalent means for protecting the inner tube against contact with the heads 8 of the rivets.V

'A lining 16 is arranged` inwardly from the band 5 and extends a ditance beyond the longitudinal edges thereoi0 and engages with the side walls of the tire casing-17, as clearly illustrated in Fig. 1. The lining is construeted of a plurality. of side strips 16Il of fabric arranged against the inner surfaces of the opposite side walls of the tire and abut-V ting the edges of the band 5. The side strips 16 are secured to and are connected Aby a center strip 18 consisting of one or more 'layers of fabric which entirely covers the iin-l ner surface ofthe band 5 and coacts with'the side strips to present a substantially smooth surface for contact with the inner tube (not shown). j

In' use,.tlie diameter of the band 5 is reduced by sliding the overlapped ends 7 and as clearly'illustrated in-Fig. 2 and the inner tube is positioned within thelcasing in the usual .manner and inflated, subsequently to fastening the tire casing upon the rim.

What we claim is: 1. In combination, a tire casing. an armor band arrangedin said casing, and a lining' arranged in the tire casing against the side wallsof the Vlatter and the inner surface of said band, the lining including side strips arranged` against theinner surface ol the -side walls' of the tire casing and abutting the longitudinal edges of saidband, and a center ies strip secured to and Connecting the sideu overlapped, the inner end of the band have ing longitudinally .extending slots formed therein, headed rivets Secured to the outer of the overlapped ends and slidably mounted in the slots, and a housing secured to the inner end of the band and positioned over the slots to in ease the rivets to prevent the same from eoinlng in Contact with the inner tube 0f the tire, and a lining engaged Witlithe inner surface of said band.

In testimony whereof We have afiixed our signatures in presence of two Witnesses.
